Subsumption checking between concept queries in different ontologies based on mutual instances
This paper proposes a checking method based on mutual instances and discusses three key problems in the method: how to deal with mistakes in the mutual instances and how to deal with too many or too few mutual...

BP network based users’ interest model in mining WWW Cache
By analyzing the WWW Cache model, we bring forward a user-interest description method based on the fuzzy theory and user-interest inferential relations based on BP (back propagation) neural network. By this me...

Concept approximation between fuzzy ontologies
Fuzzy ontologies are efficient tools to handle fuzzy and uncertain knowledge on the semantic web; but there are heterogeneity problems when gaining interoperability among different fuzzy ontologies. This paper...

Obtaining profiles based on localized non-negative matrix factorization
Nonnegative matrix factorization (NMF) is a method to get parts-based features of information and form the typical profiles. But the basis vectors NMF gets are not orthogonal so that parts-based features of in...

Bridge ontology: A multi-ontologies-based approach for semantic annotation
Representing the relationships between ontologies is the key problem of semantic annotations based on multi-ontologies. Traditional approaches only had the ability of denoting the simple concept subsumption re...

Dependence analysis based on dynamic slicing for debugging
Dynamic program slicing is an effective technique for narrowing the errors to the relevant parts of a program when debugging. Given a slicing criterion, the dynamic slice contains only those statements that ac...
